As these numbers show, Crosby had the best statistical prime between the two as of now, but many fans still believe that McDavid's outrageous 153 points this past season beats out Crosby in terms of being the best.
Despite every NHL fan having their own opinion and regardless of how similar they all may sound, we will never ever truly have a definite answer to this debate. Both McDavid and Crosby are forever going to be known for changing the sport of hockey once their careers are over, but it seems to be one will not be identified as "better overall" than the other. Nonetheless, the controversy stays alive indefintely.
